Bill Coogan was a character in the Bashir 62 holosuite program.
Coogan was the manager of the Shining Oasis Hotel and Casino. On one occasion when Vic Fontaine did not show up to perform, Coogan went to his hotel room and found it ransacked and Vic missing. Coogan called the police, but they could not determine what had happened to Vic. Coogan had to hire another singer to perform in the lounge. (DS9 novel: The Long Mirage)
